I'm looking studies on the association between forest primary productivity and alpha diversity specially to the tropical and subtropical forests.
Ohhh! Geraldo...
You are asking for "the formula of happiness"!!!
This correlation is practically unprovable. It is relatively simple to study production/productivity, in monospecific forests (I have several papers in R.G. that you can see). But it is very difficult to study in multispecific forests. And much more, in megadiverse forests.
It is a pleasure to know that you are alive! Warm regards.

You'll find it in the paper by
Liang et al. 2016. Positive biodiversity-productivity relationship predominant in global forests. Science 354: 196-207. DOI: 10.1126/science.aaf8957
This paper deals with global patterns but tropics are of course part of it.

Yes, it makes sense, especially if many plants can occupy similar niches. I say yes!
Hi Geraldo! Our latest research shows no relationship between functional diversity and biomass stocks in subtropical forests (Article Climate and large-sized trees, but not diversity, drive abov...
). However, in a previous study we found some relationships among species diversity and biomass increment and mortality rates in a subtopical forest remnantArticle Drivers of subtropical forest dynamics: The role of function...
.Hope to contribute with the discussion!
Best regards!
The niche complementarity hypothesis also postulates, higher production due to higher functioning of community through efficient utilization of resources by coexisting species (Tilman, 1999)
Hi, in a review on this topic, I found that tree diversity-productivity relationships sometimes exist in tropical forests, although effects tend to be weaker/less consistent than in temperate regions: Article Biodiversity and ecosystem functioning in naturally assemble...

We found evidence for a positive diversity-productivity relationship (up to 50% higher tree productivity in the most diverse stands) in the oldest tropical tree diversity experiment:
